# How to Install HTTP/2 in WebHost Manager (WHM)

If you have just purchased your VPS or Dedicated server account, then congratulations you do not need to install **HTTP/2** as it is already included. However, if you need to install it then it is a fairly simple process. You will need to have [EasyApache 4](/support/edu/easyapache/upgrade-php-easyapache/) please review the instructions and conditions below if you need to install **HTTP/2**.

## Install HTTP/2

The **installation of HTTP/2** on a [VPS](https://www.inmotionhosting.com/vps-hosting) or [Dedicated server](https://www.inmotionhosting.com/dedicated-servers) account requires that you have root access. Make sure that you have also performed a complete backup before continuing.

1. [Login to SSH as the root user](/support/server/ssh/how-to-login-ssh/)
2. Run the following command:yum install ea-apache24-mod_http2

## Enable HTTP/2 in Easy Apache4

1. [Log into Web Host Manager (WHM)](https://www.inmotionhosting.com/support/edu/whm/log-into-whm/)
2. Select **EasyApache 4**
3. Beside *Currently Installed Packages*, select **Customize**
4. Select **Apache Modules**
5. Search “http2”
6. Toggle **mod_http2** to blue

## Important conditions for HTTP/2 installation

- If you are using NGINX web server configured for port 80, you do not need to install **HTTP/2** support for Apache as it is included in the default NGINX configuration. The installation of **HTTP/2** in this type of configuration will cause secure connection issues with the Apple Safari internet browser in the Mac Operating System (OS 10+).
- If you install [NGINX](/support/server/nginx/install-nginx-on-cpanel/) for your InMotion Hosting account, then it will automatically remove the **HTTP/2** package for the Apache Web Server.
- Remember that the domain using **HTTP/2** must have a valid SSL certificate for **HTTP/2** to work properly.
- Apache offers three MPM modules: Prefork, Worker, and Event. **HTTP/2** on Apache does not support the *mpm_prefork* module but you can use **mpm_worker** in its place. You can find more information on the different Multi-processing Modules (MPM) [here](https://httpd.apache.org/docs/2.4/mpm.html). The removal of the mpm_prefork module will affect how your PHP code is handled. If you are not familiar with the multiprocessing modules and how it affects your PHP installation then consult with an experienced developer. You can also find more information on the different PHP handlers in this article: [Choosing the best PHP handler](/support/website/choosing-the-best-php-handler/).You can remove the mpm_prefork module by using the following command: yum remove ea-apache24-mod_mpm_prefork

You should now be able to **install HTTP/2 support on your VPS/Dedicated server account**. For further reading on enabling HTTP/2 in Apache, please see [How to enable HTTP/2 support in Apache](https://www.inmotionhosting.com/support/server/apache/enable-http-2-apache/).
